You cannot go wireless to wireless with routers. If you need to extend or go wireless from the router to another you need a bridge or extender.
Not entirely true. I'm using bridge mode on my 2nd floor Lynksis router to maintain the same subnet being dished out by my basement located ISP provided router/modem. I wasn't getting a good signal on other floors from my basement utility room. It just took some digging in Google to find how to set it up appropriately.
